Add a BUF_INIT macro, which makes it easier to initialize a struct buf to an empty string (without a heap allocation). Add buf_move() to move the contents of one struct buf to another (the source is reset to BUF_INIT, analogous to C++ move-assignment). Use buf_reset() instead of directly calling `free(s->buf)` since the internal buf may not always be allocated by malloc() now.
